Very interesting article.

At United, says a spokesman, captains of 747-400s average only three
takeoffs and landings a month. Co-pilots, because there are three of them
aboard each flight, get even less practice, averaging just one takeoff and landing
a month. Because of scheduling complexities and vacations, some co-pilots
don't make a takeoff and landing for months.

I thought about this problem in the past. With the B787-9, B772LR or the A380 things are only going to get worse with this aspect (and the passengers think they can trust the crew in the cockpit).

The carrier is showing the video to all its pilots, and re-emphasizing certain
flying rules. One rule: the rudder (not ailerons) must be used to maintain
direction when an engine fails on takeoff.

This one confuses me. I'm sure we all remember the A300 crash in New York (AA587) 2 months after 9/11. The reason for the crash was using the rudder.
I now there is a difference because United had an engine problem and American didn't but does it matter?
Here we have 2 kind of similar incidents and the conclusion of them are conflicting orders.
Are we setting rules now according to the last accident / incident (and forgetting everything before that)?

Lurching over South San Francisco, then Daly City and San Francisco, the jet
was so low it terrified residents. At the airport, a telephone hot line recorded a
deluge of complaints. … The jet set off car alarms, "it shook the whole house,
we thought it was going to take out the neighborhood," said another caller.

I now that feeling :-). About 5 years ago, at around 03:00 an Israeli Air Force B707 came very very very low above my house. I don't think there was a single person who didn't wakeup by this. I was sure he was going down. Since it was an Air Force flight no details of the incident were published.

P.S. I don't believe its 04:50 already.
